Nambu Ironware —
The Cast-Iron Kettle Worth Its Weight in Luggage

900 Years of Iron · Tetsubin vs Teapot · Real vs Tourist Grade · Care for Life

The Heaviest Good Decision You’ll Make

Of all Japan’s crafts, Nambu tekki — the cast ironware of Morioka and Mizusawa in Iwate — asks the most of your luggage allowance and repays it longest. A proper tetsubin kettle, cared for, outlives its buyer; antique ones from the Meiji era still boil water beautifully. The craft grew here from the 1600s under the Nambu lords, drawing on local iron sand, river clay and lacquer — and it still centers on the two towns the Tohoku Shinkansen conveniently strings together: Morioka and Mizusawa.

Know What You’re Buying

🍵 Tetsubin (the real kettle)

Raw cast iron inside, heated directly on flame or induction, adding a trace of iron to the water — tea people swear the water tastes rounder. Needs simple care: dry it fully after each use, never scrub the inside, let the mineral layer build. ¥15,000 (approx. $100)–100,000+ from working foundries.

🎫 Enameled iron teapot (kyūsu)

The colorful pots sold worldwide: enamel-lined, brew-only (never on flame), zero maintenance. Honest products — just know the difference; if the inside is glossy black or colored, it’s enamel.

The Names That Matter

Kamasada (Morioka) — Nobuho Miya’s minimalist designs made Nambu iron contemporary; the workshop shop in Morioka’s craft quarter is a pilgrimage. Iwachu (Morioka) — the big, reliable house with a factory showroom and export experience. Oitomi (Mizusawa) — the historic foundry town’s stalwart. Around them, dozens of small kobo sell direct at fair prices.

Practicalities

Weight: a 1.2 L tetsubin runs 1.5–2 kg — checked luggage, wrapped in clothes, dead center. Induction: most tetsubin work on IH — confirm the base diameter. Rust: surface rust is normal and fixable (boil tea leaves in it — the tannin seals it); it is a feature of ownership, not a defect. Shops ship internationally if the scale says no.
